In this case crashes have absobule random nature.
Now time (at morning) i load 10 clients (5 on PC, 5 on laptop, all have same OS - Win 10) and have no crashes too after like ~2 hours (i use many commands like /market , /shop etc in each client of course). Yesterday at morning (like today) i have 2 crashes after like ~2-5 minutes when i load all clients and i don't use any commands in this clients (simple load clients) =/
Also, for example now time i do test - use clicker on two random clients (1 on PC and 1 on laptop) with simple macro for non-stop spam /find command and after ~2 hours i don't have any problem with this clients. I'm lost in thought =/
ps fking IMC weekly updates, don't have any problem before 02.05.2018
